RESEARCH

My research focuses on heavy-quark physics and hadron structure, using Lattice QCD to provide first-principles predictions for form factors and Standard Model parameters. The underlying goal is to support and interpret experimental results, providing theoretical input for non-perturbative quantities and helping to shed light on existing anomalies that may signal new physics.
